SN74HCT08NE4

Inverter Gates Overview

The SN74HCT08NE4 is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs with low input current. The device provides an output drive capability of ±4mA at 5V and supports up to 10 LSTTL loads. Typical propagation delay is 13ns, with maximum values reaching 27ns at 5.5V. It consumes a maximum supply current of 20µA and functions reliably across an operating temperature range of -40°C to 85°C.

Inverter Gates Procurement Notes

Verify the package type matches the required PCB footprint, as the SN74HCT08 series is available in multiple configurations including SOIC, SSOP, PDIP, and TSSOP. Confirm that the specific ordering suffix corresponds to the desired packaging format and lead finish. Ensure the component meets RoHS compliance requirements if applicable to the manufacturing process. Check for any specific environmental or handling precautions noted in the datasheet.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are necessary for CMOS logic applications. It is suitable for designs requiring moderate speed with typical propagation delays around 13ns. Consider the PDIP package for through-hole mounting needs. Verify that the 4.5V to 5.5V supply voltage range aligns with the system power rails. Evaluate thermal performance if operating near the upper temperature limits.

Inverter Gates Part Context

This part belongs to the SN74HCT08 family of quadruple 2-input positive-AND gates. The 'N' suffix indicates a 14-pin PDIP package, while 'E4' denotes lead-free composition compliant with RoHS standards. Texas Instruments produces this series to bridge TTL and CMOS logic families, offering robust performance in standard digital environments.

Inverter Gates Replacement Considerations

SN74HCT08N is a direct equivalent with identical electrical characteristics and pinout. SN74HC08 variants offer wider voltage ranges but lack TTL compatibility. SN74ALS08 provides higher speed but different power characteristics. Verify package dimensions and pin assignments before substitution.
